No known errata.
Interrupts may be lost when writing the timer registers in the asynchronous timer
ATmega169A/169PA/329A/329PA/649A/649P/3290A/3290PA/6490A/6490P
The interrupt will be lost if a timer register that is synchronous timer clock is written when the
asynchronous Timer/Counter register (TCNTx) is 0x00.
Problem Fix/ Workaround
Always check that the asynchronous Timer/Counter register neither have the value 0xFF nor
0x00 before writing to the asynchronous Timer Control Register (TCCRx), asynchronous
Timer Counter Register (TCNTx), or asynchronous Output Compare Register (OCRx).
